ITU meets to define 4K and 8K UHDTV parameters – Engadget

My comments

We are starting to see the arrival of ultra-high-definition video displays being available for general-purpose computing requirements. This yields cinema-quality vision experience as if normally seen directly by the eye.

But the concept has existed in a general form where a well-bred current-generation digital still camera is able to take an image with that resolution. As well, some screens used in particular industries like medical imaging are implementing this kind of pixel-dense display. Similarly, some video setups like the recent practice of exhibiting performances of opera or classic plays in the cinema through the use of video links use the ultra-high-definition setups.

The technology is also being assisted through the availability of pixel-dense display technology in computer devices. Examples of this include Apple’s “Retina” technology used in the latest iPhone and iPad devices and starting to appear across some of Apple’s 13” MacBook computers. This could be implemented in larger display areas like flatscreen TVs and desktop monitors.

Here, a particular resolution and aspect ratio needs to be called for both the 4K and 8K displays. This may be a point to bring in the 21:9 display ratio used for cinema applications; and could help with providing an improved video experience for the films that were used to showcase Cinemascope or Panavision.

But after 1080p (1920×1080) was called as a standard for HDTV displays, which has allowed a point of reference to be used for this application; there needs to be a standard for this kind of ultra-high-definition display. This can allow the displays to be marketed properly such as with a standard logo that applies to equipment that meets one or more of the criteria.

This may also affect how visual layouts are worked on so we can think more of display physical sizes and application classes rather than particular resolutions. It will also mean the use of vector-based user-interface displays or graphics assets that suit particular display densitys as what is being put forward for Windows 8 software design.
